Description

Technical Field

[0001] This utility model relates to the field of fresco towel production technology, specifically a fresco towel folding machine with mechanical adhesive application. Background Technology

[0002] A surgical drape is a surgical drape specifically designed for performing surgery on a patient at a specific site. This drape has holes made for specific surgical locations, allowing the surgeon to perform the operation through these pre-set holes. Early surgical drapes were mainly made of cotton cloth.

[0003] The existing Chinese utility model patent with publication number CN216335743U discloses an adhesive-applied fresco towel folding machine, including an adhesive-applied fresco towel folding machine base. The base has legs at its bottom, a first fixed seat at its top, a second fixed seat on one side of the first fixed seat, a third fixed seat fixedly connected to one side of the second fixed seat, a fourth fixed seat on the right side of the third fixed seat, and a fifth fixed seat on the right side of the fourth fixed seat away from the base. A hydraulic cylinder is mounted on the first fixed seat, and a first double-sided adhesive is rotatably connected above the hydraulic cylinder. A first disc is hinged to the bottom plate of the worktable of the first fixed seat, and a second disc is hinged to the surface of the worktable. This utility model achieves the purpose of automatically adding adhesive, folding, and imprinting patterns on fresco towels during processing.

[0004] Before use, surgical drapes need to be bonded to the interlayer and non-woven fabric. To accommodate the perforated structure of the drape, the non-woven fabric and interlayer of the drape are usually laid flat and sprayed with adhesive. After bonding, they are fed into a folding machine for folding. This method has low production efficiency and the drape may unfold after folding. Utility Model Content

[0010] As a preferred embodiment of this utility model, the limiting shaft is symmetrically installed inside the connecting frame and below the plate-like structure of the support frame. The limiting shaft is symmetrically installed between the plate-like protrusions on the left and right sides above the support frame. The limiting shaft can restrict the position of the drape.

[0011] As a preferred embodiment of this utility model, the electric actuator is symmetrically installed on the left and right sides inside the support frame with the center of the support frame flat structure as the reference. The connecting block is symmetrically installed on the left and right sides of the plate-shaped protrusions on the upper and lower sides of the support frame. The electric actuator can drive the connecting block to reciprocate left and right.

[0012] As a preferred embodiment of this utility model, a bracket is fixedly installed above the support frame, a gantry frame is fixedly installed above the bracket, a limit rod is fixedly installed below the gantry frame, a pressure roller is movably installed at the bottom end of the limit rod, a connecting shaft is fixedly installed on the rear side of the bracket, an adapter block is fixedly installed on the outer side of the connecting shaft, a limit post is movably installed at the end of the adapter block, and a folding machine is fixedly installed above the base plate; the folding machine is capable of folding and conveying the fresco towel to the top of the chute.

[0014] As a preferred embodiment of this utility model, the sliding grooves are symmetrically installed on the front and rear sides of the fixed frame, with the rear sliding groove being lower than the front sliding groove. The pressing shaft is rotatably connected to the support block and the limiting block. The rotating shaft of the drive motor is fixedly connected to the corresponding pressing shaft. The support block can limit the position of the drive motor.

[0015] Compared with the prior art, this utility model provides a folding machine for burlap drapes that can be mechanically adhesiveted, which has the following advantages:

[0016] 1. This utility model utilizes an electric actuator, which is symmetrically installed on both sides of the support frame's flat structure, with the center as the reference. Connecting blocks are symmetrically installed on the left and right sides of the plate-like protrusions on both sides of the support frame. The non-woven fabric and interlayer of the drape on both sides of the drape wrap around from below the limiting shaft under the connecting frame to behind the limiting shaft inside the protrusion at the rear end of the support frame. They then move upwards around the limiting shaft at the rear end of the support frame, and finally, through the limiting shaft inside the support frame, separate the non-woven fabric and interlayer of the drape, ensuring that the bottom non-woven fabric is located below the electric actuator. The central interlayer is located below the electric push rod above the support frame, and the top non-woven fabric is located above the two limiting shafts on the front and rear sides of the top of the support frame. The glue spraying head inside the connecting block on the inner wall of the support frame can spray glue onto the bottom non-woven fabric and the left and right sides of the interlayer. The electric push rod can drive the connecting block to move back and forth left and right. By adjusting the extension and retraction speed of the electric push rod to half the speed of the perforated cloth, the relative displacement path between the electric push rod and the perforated cloth when driving the connecting block to move back and forth left and right is in a half circle, so as to spray glue onto the edge of the perforated cloth opening structure. After the glue spraying is completed, the cloth is re-stacked between the clamping rollers for bonding, thereby improving production efficiency.

[0017] 2. This utility model, through the setting of the sliding groove, allows the drape to be discharged above the sliding groove after passing through the folding machine. The position of the pressing piston is restricted by the fixing frame. The pressing shaft is movably installed inside the limiting block and the support block. The limiting block is fixed to the bottom end of the pressing piston. The extension and retraction of the pressing piston drives the support block to move downward, adjusting the relative pressure between the rubber sleeves on the outside of the pressing shaft. After the drape is folded, it slides through the sliding groove between the rubber sleeves. The driving motor drives the pressing shaft to rotate, causing the drape to pass between the pressing shafts and be pressed, preventing the drape from unfolding after folding.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1 - Figure 4In this embodiment, a folding towel machine capable of mechanically applying adhesive includes: a base plate 1, a connecting frame 11 fixedly installed above the base plate 1, a support frame 12 fixedly installed above the connecting frame 11, a limiting shaft 13 movably installed inside the connecting frame 11 and the support frame 12, an electric push rod 14 fixedly installed inside the support frame 12, a connecting block 15 fixedly installed inside the support frame 12 and at the end of the electric push rod 14, an adhesive spray head 16 fixedly installed inside the connecting block 15, a guide frame 17 fixedly installed at the front end of the base plate 1, a clamping roller 18 movably installed inside the guide frame 17, and a guide shaft 19 movably installed inside the guide frame 17 and at its top.

[0027] The support frame 12 has a raised structure at its rear end, a horizontal plate-like structure at its center, and vertical plate-like structures at its left and right ends on both sides. The limiting shaft 13 is symmetrically installed inside the connecting frame 11 and below the plate-like structure of the support frame 12. The limiting shaft 13 is symmetrically installed between the plate-like protrusions on the left and right sides above the support frame 12. The electric push rod 14 is symmetrically installed on the left and right sides inside the support frame 12 with the center of the flat plate structure of the support frame 12 as the reference. The connecting block 15 is symmetrically installed inside the plate-like protrusions on the left and right ends of both sides of the support frame 12.

[0028] Specifically, by restricting the position of the limiting shaft 13 through the connecting frame 11 and the support frame 12, the non-woven fabric and interlayer of the upper and lower sides of the drape are made to wrap around from below the limiting shaft 13 under the connecting frame 11 to behind the limiting shaft 13 inside the rear protrusion structure of the support frame 12, and then wrap around the limiting shaft 13 at the rear end of the support frame 12 from bottom to top. The non-woven fabric and interlayer of the upper and lower sides of the drape are separated by the limiting shaft 13 inside the support frame 12, so that the bottom non-woven fabric is located below the electric push rod 14 below the support frame 12, the middle interlayer is located below the electric push rod 14 above the support frame 12, and the top non-woven fabric is located below the support frame 12. Above the two limiting shafts 13 on the front and rear sides of the top, it is convenient to spray glue on the upper surface of the bottom non-woven fabric and the upper surface of the interlayer. The electric push rod 14 can drive the connecting block 15 to move back and forth. By adjusting the extension speed of the electric push rod 14 to half the speed of the drape, the electric push rod 14 and the relative displacement path of the drape are in a half circle when the connecting block 15 moves back and forth, so as to spray glue on the edge of the opening structure of the drape. After the glue is sprayed, it is stacked again between the clamping rollers 18 for bonding. Finally, it moves backward to the top of the bracket 2 through two 90-degree bends formed by the guide shaft 19.

[0029] A bracket 2 is fixedly installed above the support frame 12, a gantry frame 21 is fixedly installed above the bracket 2, a limit rod 22 is fixedly installed below the gantry frame 21, a pressure roller 23 is movably installed at the bottom end of the limit rod 22, a connecting shaft 24 is fixedly installed on the rear side of the bracket 2, an adapter block 25 is fixedly installed on the outer side of the connecting shaft 24, a limit post 26 is movably installed at the end of the adapter block 25, and a folding machine 27 is fixedly installed above the base plate 1.

[0030] Specifically, the bracket 2 can restrict the deformation of the drape. The position of the limiting rod 22 is limited by the gantry 21. The pressure roller 23 is fitted into the inside of the bracket 2. After the drape passes under the pressure roller 23, it can be bent with the left and right ends of the pressure roller 23 as the reference. The limiting post 26 is installed above the connecting shaft 24 on the left and right sides at equal distances through the adapter block 25. The limiting post 26 changes from a vertical state to a horizontal state from front to back. After the left and right sides of the drape are bent by the pressure roller 23, they are in a vertical state. After passing the rear limiting post 26, the left and right sides are folded towards the center in sequence. Then, it enters the conveyor belt of the folding machine 27 for folding. After passing through the folding machine 27, it will be discharged above the chute 33.

[0031] A fixing frame 3 is fixedly installed on the top of the base plate 1. A pressing piston 31 is fixedly installed below the fixing frame 3. A limit block 32 is fixedly installed at the lower end of the pressing piston 31. Slide grooves 33 are fixedly installed on both sides of the fixing frame 3. A support block 34 is fixedly installed on the top of the base plate 1. A drive motor 35 is fixedly installed on the top of the support block 34. A pressing shaft 36 is movably installed inside the support block 34 and inside the limit block 32. A rubber sleeve 37 is fixedly installed on the outside of the pressing shaft 36.

[0032] The fixed frame 3 is symmetrically installed on the top of the base plate 1 with the center of the lower pressure shaft 36 as the reference. The lower pressure piston 31 is symmetrically installed on the bottom of the left and right fixed frames 3. The sliding groove 33 is symmetrically installed on the front and rear sides of the fixed frame 3, and the rear sliding groove 33 is lower than the front sliding groove 33. The lower pressure shaft 36 is rotatably connected with the support block 34 and the limit block 32. The rotating shaft of the drive motor 35 is fixedly connected to the corresponding lower pressure shaft 36.

[0033] Specifically, the position of the pressing piston 31 is restricted by the fixing frame 3, and the pressing shaft 36 is movably installed inside the limiting block 32 and the support block 34. The limiting block 32 is fixed to the bottom end of the pressing piston 31. The extension and retraction of the pressing piston 31 drives the support block 34 to move downward, adjusting the relative pressure between the rubber sleeves 37 on the outer side of the pressing shaft 36. After the drape is folded, it will slide through the slide groove 33 to the rubber sleeves 37. The driving motor 35 drives the pressing shaft 36 to rotate, so that the drape passes between the pressing shafts 36 and is pressed to prevent the drape from unfolding after folding.

[0034] In use, the electric actuator 14 is symmetrically installed on the left and right sides inside the support frame 12, with the center of the flat structure of the support frame 12 as the reference. The connecting block 15 is symmetrically installed on the left and right sides of the plate-shaped protrusions on the upper and lower sides of the support frame 12. The non-woven fabric and interlayer of the drape on the upper and lower sides are wrapped around the lower limit shaft 13 of the connecting frame 11 to the rear of the limit shaft 13 inside the protrusion of the support frame 12, and then wrapped around the limit shaft 13 at the rear of the support frame 12 from bottom to top. The non-woven fabric and interlayer of the drape on the upper and lower sides are separated by the limit shaft 13 inside the support frame 12, so that the bottom non-woven fabric is below the electric actuator 14 below the support frame 12, the middle interlayer is below the electric actuator 14 above the support frame 12, and the top non-woven fabric is above the two limit shafts 13 on the front and rear sides of the top of the support frame 12. The glue spray head 16 inside the connecting block 15 on the inner wall of the support frame 12 can spray glue on the left and right sides of the bottom non-woven fabric and interlayer. The electric actuator 14 can drive the connecting block The electric push rod 14 reciprocates about 15 times. By adjusting the extension and retraction speed of the electric push rod 14 to half the speed of the drape, the electric push rod 14 and the drape form a half-circle relative displacement path when the electric push rod 14 drives the connecting block 15 to reciprocate about 15 times. This allows for the application of adhesive to the edges of the drape's perforated structure. After the adhesive is applied, the drape is re-stacked between the clamping rollers 18 for bonding, thereby improving production efficiency. After passing through the folding machine 27, the drape is discharged above the slide 33. The position of the pressing piston 31 is restricted by the fixing frame 3. The pressing shaft 36 is movably installed inside the limiting block 32 and the support block 34. The limiting block 32 is fixed to the bottom end of the pressing piston 31. The extension and retraction of the pressing piston 31 drives the support block 34 to move downward, adjusting the relative pressure between the rubber sleeves 37 on the outside of the pressing shaft 36. After the drape is folded, it slides through the slide 33 between the rubber sleeves 37. The driving motor 35 drives the pressing shaft 36 to rotate, causing the drape to pass between the pressing shafts 36 for pressing, preventing the drape from unfolding after folding.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
